The purpose of this study was to examine the acute effects of the French Contrast Training protocol on agility and vertical jump performance in soccer players and to compare its outcomes with those of a traditional Post -Activation Potentiation (PAP) protocol. A total of 30 male soccer players with a mean age of 19.93 +/- 1.43 years participated in the study. The study employed an experimental research design. Following a standard warm -up, each participant underwent both a traditional PAP protocol and a French Contrast Training protocol, respectively. Physical performance was then assessed using the countermovement jump (CMJ), squat jump, pro -agility test, and Illinois agility test. For parame tric data, repeated measures ANOVA with Bonferroni correction was applied, while for non -parametric data, the Friedman and Wilcoxon tests were used. The French Contrast protocol produced statistically significant improvements in CMJ height, flight time, pe ak and average power, as well as in pro- agility and Illinois agility performance (p<0.05). No significant difference was observed in the squat jump test. These findings suggest that the French Contrast protocol may more effectively activate the neuromuscul ar system in the short term. The findings indicate that the French Contrast Training protocol may elicit positive acute effects on certain performance parameters in soccer players. Improvements observed in vertical jump and agility tests suggest its potential as a pre -competition activation strategy. However, further research is warranted to generalize these results across different populations and training contexts.
